gauge, gage

1. The thickness of sheet metal or metal tubing, usually designated by a number.

2. The diameter of wire or a screw, usually designated by a number.

3. The distance between two points, such as parallel lines of connectors.

4. A strip of metal or wood used as a guide to control the thickness of a bituminous or concrete paving; called a screed when used in plastering.

5. A measuring instrument, esp. one for measuring liquid level, dimensions, or pressure.

6.See mortise gauge.

7. In roofing, the length of a shingle, slate, or tile that is exposed when laid.

8. The quantity of gauging plaster used with common plaster (lime putty) to hasten its setting, etc.

9. To mix gauging plaster with lime putty, to effect better control of the set, to prevent shrinkage of the lime putty, and to increase its strength.

Gage 

(Russian, shablon), in engineering, a device or tool for checking the accuracy of the shape of various finished items; a standard to which uniform items are manufactured.

A radius gage is an instrument for checking the profile radii of curvature of convex and concave surfaces of machine parts and other items. It is a steel plate 0.5–1 mm in thickness with a convex or concave curvature at the end. The circular radii are from 1 to 25 mm. The gage is positioned next to the item in order to check the radius of curvature. Any deviation from the radius of curvature of the gage is judged by the gap.

A thread gage is a device for determining thread pitch and angle. It consists of a steel plate 0.5–1 mm thick with teeth designed to fit the axial profile of a thread. There are gages for checking threads in inches and in the metric system. The gage is placed against the thread to be checked in such a way that the gage teeth enter the depressions in the thread. The correspondence of the pitch and angle of the thread to those of the gage is determined by the gap or by the tightness of fit.
